FWIK 

Short for Friends With Inside Knowledge. This is used to describe friends who are emotionally attracted to each other but resist any type of physical advancements either because they find each other ugly or just because they think they shouldn't.

Jenny and Johnny were rumored to be FWIK's because they always had Starbucks together.
